PROBLEM TO BE SOLVED: To save a power consumption in the waiting state of an electrical apparatus. SOLUTION: A microcomputer which controls respective electrical components is incorporated in a circuit board to which a hot water washer, a heated toilet seat and a remote control unit are connected and a main power supply unit for receiving a power from an external power supply is provided. A switching device is provided in the middle of a circuit, with which the main power supply unit is connected to a commercial power supply and connected to the microcomputer. An auxiliary power supply unit composed of a small size transformer is connected to the microcomputer. If a power supply switch is turned off for stopping an electric apparatus, an OFF operation signal is outputted to the switching device from the microcomputer, and the switching device cuts off the connection between the commercial power supply and the main power supply current application to the main power supply is blocked. Since the microcomputer is fed with a power by the auxiliary power supply unit in this waiting state, when the power supply switch is turned on, an ON-operation signal is outputted to the switching device, and the connection between the commercial power supply and the main power supply can be restored. |
